Missing .rat-excludes entries for schema.graphqls files.

Also 2 failing tests:

Looks good to me, but needs some integration tests to validate the count for process instance and user task and also test some edge cases.
Rest of comments are minor, just check the possible null return for getSingleResult.
Nice work @fjtirado !

@fjtirado nice addition! Would it be possible to have it for jobs too?
